Lynne Jones: The Tories oppose the national health service, so it is not surprising that they oppose the national care service. The current lottery of life, under which one in three who develop a severe condition lose everything and the rest keep their wealth intact, is unfair and should not be tolerated in a civilised society. I favour an approach of solidarity. Should we not go out and advocate the comprehensive approach, which also seems to be the lowest-cost option, and develop a groundswell of public opinion behind that option so that no future Government can ignore it?
